Description

Technical Field

[0001] The utility model relates to the technical field of thread rollers, in particular to a thread roller repairing device. Background Art

[0002] During the production and processing of cigarette filter rods, the tow needs to be loosened, that is, the tightly connected tow belts delivered are loosened and unfolded to ensure the subsequent filter rod forming and processing. This process is the key process of filter rod forming. Usually, the threaded roller and rubber roller are pressed together, the tow is clamped between the two, and the passing tow is horizontally loosened by rolling and threading. The threads alternately clamp and release the tow fibers, and the tow belt is evenly unfolded and relaxed. The curled parts are interlaced with each other and their arrangement is disrupted, so that the tow is fully stretched and curled.

[0003] At present, when the thread roller and rubber roller are used together, the wire bundle will inevitably be entangled with the roller. Usually, the operator uses sharp tools (such as blades, scissors, etc.) to deal with the entanglement of the roller. However, the long-term sliding of the sharp tool is likely to cause burrs, scratches and other defects on the thread roller, making the thread roller entanglement phenomenon more frequent. In order to ensure the smoothness of the thread roller structure and avoid the increase in cost caused by replacing a new thread roller, the operator usually uses sandpaper or a scraper to grind the thread roller. Manual grinding is labor-intensive, takes a long time to work, has low grinding efficiency and poor repair effect. Utility Model Content

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0031] like Figures 1 to 5As shown, the thread roller repair device of the embodiment of the utility model comprises a mounting seat 1 and a clamping mechanism 2, a first driving member 3 and a repairing member 4, all of which are arranged on the mounting seat 1. The clamping mechanism 2 comprises a second driving member 21 and two clamping blocks 22. The two clamping blocks 22 are spaced apart along a first direction to form a clamping groove 23 for clamping the thread roller 100 (the first direction is the X direction shown in the figure). At least one of the two clamping blocks 22 is a movable clamping block. The second driving member 21 is transmission-connected to the movable clamping block to selectively clamp or release the thread roller 100. The repairing member 4 is arranged on one side of the thread roller 100 along a second direction (the second direction is the Y direction shown in the figure). The first direction is arranged at an angle to the second direction. The first driving member 3 is used to drive the thread roller 100 to rotate so that the repairing member 4 grinds the thread roller 100. The first driving member 3 drives the thread roller 100 in the clamping mechanism 2 to rotate, so that the thread roller 100 can be polished and repaired by the repair member 4, thereby realizing automatic polishing of the thread roller 100, with good polishing effect, convenience and speed, saving time and effort, effectively improving the polishing efficiency of the thread roller 100, and reducing replacement costs; through the setting of the clamping mechanism 2, the second driving member 21 can drive the movable clamping block to move along the first direction to adjust the size of the clamping groove 23, thereby realizing the clamping of thread rollers 100 of different lengths, with strong compatibility, effectively expanding the scope of application of the thread roller repair device.

[0032] Optionally, the mounting seat 1 includes a base plate 11 and two mounting plates 12 arranged on the base plate 11 at intervals along the first direction, the two mounting plates 12 are spaced to form a receiving groove 13, the first driving member 3 and the second driving member 21 are respectively arranged on the two mounting plates 12 and are both located outside the receiving groove 13, the two clamping blocks 22 are respectively a movable clamping block and a fixed clamping block, the movable clamping block is rotatably connected to the driving end of the second driving member 21, and the fixed clamping block is connected to the driving end of the first driving member 3. By arranging the first driving member 3 and the second driving member 21 outside the receiving groove 13 and arranging the grinding area inside the receiving groove 13, the first driving member 3 and the second driving member 21 can be protected by the mounting plate 12, the influence of impurities generated by the repairing member 4 grinding the thread roller 100 on the driving member is reduced, and the service life of the driving member is increased. Of course, the first driving member 3 and the second driving member 21 are arranged opposite to each other, and the two clamping blocks 22 are respectively arranged on the two driving members, that is, the active rotation mechanism of the thread roller 100 is combined with the clamping mechanism 2, so that the thread roller 100 can be clamped and rotated at the same time, thereby reducing the occupation of the structural space.

[0033] Furthermore, the clamping block 22 includes a clamping body and a plug-in portion, the clamping body is connected to the driving member, the plug-in portion is plugged into the center hole of the thread roller 100, and the plug-in portion is provided with a guide surface 221, the guide surface 221 is inclined from one end of the plug-in portion close to the clamping body toward one end away from the clamping body and toward the rotation axis of the clamping block 22, and the guide surface 221 is used to slide with the hole wall of the center hole. By setting the guide surface 221, the guidance of the thread roller 100 during installation is strengthened, so that the thread roller 100 can be smoothly pressed by the clamping block 22.

[0034] Furthermore, the center hole is a circular hole, a triangular hole, a square hole, a pentagonal hole, a hexagonal hole or other polygonal hole, and the guide surface 221 is a conical surface. Preferably, the center hole is set as a circular hole, and by setting the guide surface 221 as a conical surface, the entire circumference of the center hole can abut against the clamping block 22, thereby improving the contact point between the clamping block 22 and the threaded roller 100, thereby effectively ensuring the abutment stability between the threaded roller 100 and the clamping block 22. At the same time, the threaded roller 100 can be guided along the conical surface to the center position of the rotation axis of the clamping block 22, thereby improving the position accuracy of the installation of the threaded roller 100. In addition, the setting of the conical surface can also make at least part of the conical surface exposed outside the center hole when the clamping block 22 is inserted into the center hole, so that the clamping block 22 can adapt to the clamping of threaded rollers 100 with different center hole diameters, thereby improving the compatibility of the clamping mechanism 2. Of course, in other embodiments, the center hole can also be a polygonal hole. Correspondingly, a plurality of inclined guide surfaces 221 are provided at adjacent ends of the clamping blocks 22. Each guide surface 221 corresponds to an edge of the square hole, and no further limitation is made here.

[0035] In some embodiments, the repair component 4 includes a fixed shaft 41, a repair sleeve 42 and a stopper 43. The length of the fixed shaft 41 extends along the first direction. The fixed shaft 41 is detachably arranged on the mounting seat 1. The repair sleeve 42 is sleeved on the outer periphery of the fixed shaft 41. The stopper 43 is used to limit the relative position of the repair sleeve 42 and the fixed shaft 41. By detachably arranging the fixed shaft 41 and the mounting seat 1, it is easy to disassemble the repair component 4 to replace the repair sleeve 42, thereby improving the convenience of use of the repair component 4. By limiting the repair sleeve 42 with the stopper 43, the stability of the position of the repair sleeve 42 after adjustment along the first direction can be ensured, thereby ensuring the grinding stability.

[0036] Specifically, the two mounting plates 12 are provided with strip holes 121 along the first direction, and the length of the strip holes 121 extends along the vertical direction and passes through the top surface of the mounting plate 12 (the vertical direction is the Z direction shown in the figure). In this embodiment, the first direction, the second direction and the vertical direction are arranged perpendicularly in pairs. The repair part 4 also includes a connecting nut 44, the inner side wall of the connecting nut 44 is provided with a third thread, the outer periphery of the fixed shaft 41 is provided with a first thread, the first thread and the third thread are threadedly matched, the fixed shaft 41 is placed in the strip hole 121 along the vertical direction, and the two mounting plates 12 are extended from both ends of the fixed shaft 41, and a connecting nut 44 is screwed on both ends of the fixed shaft 41, and the connecting nut 44 is screwed against the mounting plate 12 to achieve the fixation of the relative position of the fixed shaft 41 and the mounting plate 12.

[0037] Optionally, the repair sleeve 42 includes a sleeve body 421 and a frosted layer 422. The outer periphery of the sleeve body 421 is coated with a frosted layer 422. The frosted layer 422 can be used to grind the outer peripheral surface of the thread roller 100 to ensure the smoothness of the outer peripheral surface of the thread roller 100. Of course, the thread roller 100 may also include a sleeve body 421 and teeth 423. The outer periphery of the sleeve body 421 is provided with a plurality of teeth 423 at intervals along the first direction. The teeth 423 can be used to grind the thread profile of the thread roller 100 to ensure the smoothness of the thread structure. In this embodiment, the thread roller 100 is provided with a plurality of threads at intervals along the first direction, and each thread is arranged in an annular shape around the outer periphery of the thread roller 100. Therefore, when the thread roller 100 is rotated for repair, each tooth 423 is correspondingly inserted into each thread. In addition, a wool felt for polishing and cleaning can also be provided on the outer periphery of the sleeve body 421. By replacing the sleeve, the thread roller 100 can be polished to meet different requirements.

[0038] Furthermore, the outer circumference of the fixed shaft 41 is provided with a first thread, the stopper 43 is provided with a mounting hole, the fixed shaft 41 is inserted into the mounting hole, the hole wall of the mounting hole is provided with a second thread, the second thread cooperates with the first thread, and the two sides of the repair sleeve 42 along the first direction are respectively abutted with a stopper 43. That is, before the fixed shaft 41 is installed on the mounting plate 12, the repair sleeve 42 is inserted into the fixed shaft 41, and then a stopper 43 is screwed on each side of the repair sleeve 42 to limit the position of the repair sleeve 42 on the fixed shaft 41. The repair sleeve 42 with a shorter dimension along the first direction can be used to grind the local position of the threaded roller 100, thereby reducing the loss of the undamaged position of the repair sleeve 42.

[0039] Furthermore, a collecting groove 14 is recessed on the mounting seat 1, and the collecting groove 14 is used to collect the residue formed by the repairing member 4 grinding the thread roller 100. The setting of the collecting groove 14 facilitates the collection of the grinding residue for subsequent cleaning, thereby improving the cleaning convenience of the thread roller repairing device.

[0040] Optionally, the bottom of the collecting groove 14 is at least partially inclined, and along the second direction, the inclined surface of the bottom of the collecting groove 14 is inclined downward from the end close to the repairing part 4 toward the end away from the repairing part 4. By setting the bottom of the groove as an inclined surface inclined downward along the second direction, the grinding residue can slide down to the bottom along the inclined surface due to its own gravity, and the operator only needs to clean the bottom area, thereby improving the convenience of use of the thread roller repair device.

[0041] Preferably, if Figure 1 As shown, the thread roller repair device also includes a protective cover 5 detachably connected to the mounting seat 1, and the protective cover 5 at least covers the polished area of ​​the thread roller 100. By setting the dust cover, on the one hand, it can prevent operators from accidentally reaching into the rotation area of ​​the mechanism to cause damage, thereby improving the safety of the thread roller repair device. On the other hand, it can also prevent the splashing of polishing residues and ensure a good working environment. In this embodiment, the dust cover completely covers the receiving groove 13, which can effectively prevent the splashing of residues. In addition, an observation port 51 can also be provided on the protective cover 5, so that the operator can observe the polished state of the thread roller 100 in the protective cover 5.
